The pattern is written for lace weight wool.
I am an advanced beginner and was able to complete the sweater as the instructions and demonstrations by Zanete were fantastic. And support from Zanete and Liene and other testers was immediate.
I used a light 4ply, fingering weight merino/alpaca blend and by going up needle size to 3.5mm for body, colourwork and arms, gauge was achieved and the garmet remained size perfect.
I used 3mm for hem, cuffs and neckband.
A stunning pattern.
The sweater is incredibly soft. The colourwork was a delight to knit.
